i would then assume an IH 300:
pto hp of 34
engine rpm of 1750

this would mean that the IH 300 has about 155 ft. lbs. of torque if i am not mistaken. than would be the reason it is capable of pulling a 3 bottom plow.
if i am correct then could you please verify my math and if i am not, could you tell me why?
thanks

One report I have shows the 300 with the max. torque made from the belt pulley is 283.2 at 1050 engine RPM with dynamometter being turned around half the RPM as engine. Farmall 400 with 412.5 at engine RPM of 924. SM farmall 365.1 at 1064 engine RPM.

d slater, i don't believe it can have more torque than the 450 mentioned above. just doesn't seem logical. what would be nice is to see some paperwork somewhere. if anyone has this please show a link or something.

it cannot have more than the d-17 allis either. that tractor has 288 ft lbs i guess according to tractor data.com

I can't say for sure its right, all I can tell you its from Nebraska test # 538 on the Farmall 300. Unless I have a misprint it should be right. These figures won't be the same as flywheel torque. If you noticed I said the dynamometer was turning at roughly 1/2 of engine RPM from belt pulley. How was the D 17 tested for torque?
